Great story and characters
Format: Kindle
I had to see what all the hype was about and after seeing the trailer on Netflix I knew I had to read the book before I watched the movie. I have to say, this was one of the better books I've read so far this year. It's not a fast paced read but it held my interest the entire time. The characters are very well developed and I really grew to like Tova and Cameron, of course Marcellus is the star of the show and is as witty as they come. If you're looking for a good read I highly recommend this one. The octopus is a difficult creature to care for so I sincerely hope the "octopus tank craze" doesn't start over this like the "clownfish tank craze" did when Finding Nemo came out. Leave it to the expert level saltwater hobbyist to care for them or better yet, leave them in the ocean. I have to mention too that this is the author's debut novel and for a debut novel it's very impressive, I'll look for others from her in the future.

A remarkable story
Format: Hardcover
What a wonderful surprise this was! I thought Remarkably Bright Creatures was a story about a woman and an octopus, but it turned out to be so much more than that. This is Shelby Van Pelt’s first book, and I don’t think a debut has affected me like this since I read Hollow Kingdom, another story that unfolds through the eyes of an animal. The story has a bit of magical realism to it, in the sense that parts of it are told from the octopus’s point of view, but otherwise it’s simply a delightful tale about family and connections that had me ugly crying by the end of the book.
In the first chapter we meet Marcellus, a giant Pacific octopus on display in the Sowell Bay Aquarium near Puget Sound. Marcellus has been in captivity for 1,299 days, and based on his life expectancy of about four years, he believes he only has a handful of days left to live. His dreary days in a small glass enclosure are broken up by secret nighttime excursions, as Marcellus is extremely smart and has found a way out of his tank.
Tova Sullivan is a seventy-year-old woman who has been working nights at the aquarium as a cleaning lady for the past two years. Tova knows how to remove the hundreds of fingerprints on the tank walls and can polish the floors to a brilliant shine. She’s also quite fond of the sea creatures she encounters each night, especially Marcellus, and the two have formed an unusual bond since Tova saved Marcellus one night after he escaped and became entangled in a bunch of electrical cords.
Next, we meet Cameron Cassmore, a thirty-year-old man who is drifting through life with no real purpose. Cameron lives in California, and one day his aunt gives him a box of his estranged mother’s things. Inside the box he finds a photo and an old class ring, clues that could lead to the identity of his father, a man he never knew. Cameron hops on a plane to Washington state, convinced the man he thinks is his father—a rich real estate tycoon—will be so distraught over abandoning his son, he’ll shower Cam with money. At least that’s the plan.
Finally, Ethan Mack is the owner of Sowell Bay’s Shop-Way, the local grocery store. Ethan has known Tova for years and secretly has a crush on her, but Tova is much too distant to notice his interest. When Cameron shows up at the Shop-Way looking for a job, Ethan directs him to his friend who manages the aquarium, which is how Cameron and Tova meet.
Tying all these characters together is Marcellus, a remarkably bright octopus with a penchant for stealing and hoarding the treasures he finds after hours on the aquarium floor, and who just might be able to bring two people together who need each other—but don’t yet realize it.
Van Pelt’s chapters alternate among all these characters and introduce a slew of side characters as well, each one vitally important to the story. At first, we don’t realize how each character is connected to the next, but slowly the author reveals her secrets until the stunned reader begins to understand the depth of these connections. Each character is given a detailed backstory that becomes very important to the plot. Tova’s story in particular was heart wrenching, as she has experienced quite a bit of loss in her life and finds herself mostly alone in her twilight years. Luckily she belongs to a group of women who call themselves the Knit-Wits, and the four of them meet weekly to eat, drink, gossip and support each other. Tova came to America from Sweden as a little girl, so the story is filled with details about growing up with her Swedish mother and father. Even the Dala horses her mother collected play a part in the story, and I found these little details added so much richness.
At first I couldn’t figure out how Cameron fit it, but once he arrives in Sowell Bay and meets Ethan and Tova, his story takes on new meaning. Cameron meets a woman named Avery who also plays a vital part in filling in some of the missing pieces about Cameron’s father, and I loved the way the author gave even the most insignificant side characters meaning and purpose.
Van Pelt infuses her story with so many emotional moments and themes. We see how the Knit-Wits are going through the aging process, as their numbers have dwindled over the last few years. Tova is facing being alone in her old age, with no children or husband to take care of her, and so she makes the rash decision to sell her beloved house and move into a retirement community. I don’t want to give too many details about Tova’s past and her losses, because I think it’s better to discover those revelations for yourself. Let’s just say that I felt Tova’s pain and wanted nothing more than for her to be happy.
And Van Pelt includes so many funny moments in her story that kept the tone light, despite some of the more heavy themes. There’s an ongoing bit about Cameron’s lost luggage that was hysterically funny, and Tova inherits a stray cat at one point, which was a delightful side plot. I also loved the story about the t-shirt that Tova uses to clean Ethan’s kitchen—you’ll just have to read the book so you can experience the hilarity too!
And of course, I can’t forget the star of the story, Marcellus the octopus. As the days tick by—each of his chapters starts with a marker (“Day 1,299 of my captivity”, etc)---the tension builds as Marcellus gets closer to his impending death (at least that’s what he thinks). Marcellus understands human nature more than most humans, and I loved the way he wisely intuits each character’s needs. Ultimately, this is a story about creatures—both human and animal—saving each other. The way Marcellus’s story plays out was absolutely perfect—heartbreaking and heartwarming at the same time.
This is a very special book, and I’m so glad I was able to finally read it. Highly recommended!

It was as good as I'd hoped.
Format: Kindle
Marcellus McSquiddles, the giant Pacific Octopus who has lived at the Sowell Bay Aquarium for going on four years, is often exasperated with the humans who stare at him all day. But there is one human who is different. She speaks to him and more importantly, she keeps his nocturnal escapes from his tank, a secret. Tova is a gentle woman, a widower and still dealing with the loss of her son, more than thirty years ago.
When someone new strolls into town, Cameron Cassmore, looking for his dead beat father, he and Tova's lives will become inextricably linked, if they're not already. And Marcellus sees all of this and does his best to assist, where he can, since for the most part, he notices that haumans can be rather dull. But though, sometimes, especially in the case of Tova, there a a few who are remarkably bright.
This was a sweet, genuine, heartfelt and beautifully written, fun read. Van Pelt has created a delightfully jaded and long-suffering, sighing character in the form of Marcellus and he and Tova's story is told in such a unique and imaginative way. I'd been meaning to read this for so long and I'm so glad I finally did.

Remarkable book
Format: Kindle
A truly moving story. I thought going it it might be a little too sugary sweet for me, but turned out to just have the right amount of of sweetness. Marcellus is truly remarkable, although he is a bit of a spoiler, revealing the bug twist way too early, which leaves to frustration while you wait for the rest of the cast to catch up. There were a couple of cliches and the ending felt a little rushed, but still it was an enjoyable read.

Remarkably Bright Creatures
Format: Hardcover
emarkably Bright Creatures is one of those rare novels that effortlessly sneaks into your heart and makes itself at home. It centers on Tova Sullivan, a seventy‑year‑old widow quietly trying to fill the empty spaces left by loss, and Marcellus, a brilliantly observant giant Pacific octopus at the Sowell Bay Aquarium whose voice is as wise as it is wry. Their unlikely friendship is at once funny, tender, and deeply affecting, gently guiding the story through themes of grief, hope, aging, and connection.
The book also weaves in Cameron, a young man adrift in life, and slowly threads all three characters’ paths together into a quietly powerful emotional journey. What I loved most was how the narrative balances genuine humour and surprising warmth with profound reflections on family, forgiveness, and new beginnings — all without ever feeling forced or overly sentimental.
Shelby Van Pelt’s debut is beautifully written, full of subtle moments that stick with you long after the final page. Whether it’s Marcellus’s clever asides, Tova’s resilient heart, or the way the story reminds you that healing can come from the most unexpected places, this book is a joy to read.
Rating: ★★★★★ — a truly special read I’ll remember for a long time.
